Analysis Of Theoretical And Experimental Results Of Residual Stresses Due To Shipbuilding Processes

Abstract

The ship structure is subjected to many types of stresses. The history shows and proves that most of failures and cracks in ship structures are originated at the welded joints containing residual stresses. No one can deny the effect of those stresses specially in regions of tensile components which may cause the catastrophic failure of ships. This was the case of Schenectady which broken into two parts due to the act of the residual stresses. It is rather important to give a tool to take into consideration the assessment of the residual stresses. This has been done within the context of this thesis.
